Product details
Overview
MAX4612EPD+ from Maxim Integrated is a quad, low-voltage, SPST CMOS analog switch with two normally open (NO) and two normally closed (NC) channels, 100Ω max on-resistance at +5V, 4Ω max channel-to-channel on-resistance match, and rail-to-rail analog signal handling from V+ to GND. It operates from a single +2V to +12V supply and supports battery-powered audio routing and low-voltage data-acquisition systems.
For engineers reviewing the MAX4612EPD+ datasheet, MAX4612EPD+ pinout, MAX4612EPD+ application, or MAX4612EPD+ equivalent, key selection criteria include guaranteed on-resistance flatness (18Ω max), <2nA off-leakage at +85°C, TTL/CMOS logic compatibility at +5V, and 14-pin PDIP packaging for through-hole prototyping and industrial control interfaces.
Technical Context
The MAX4612EPD+ implements four independent CMOS transmission gates in a single +2V to +12V supply domain, with dedicated NO and NC configurations per pair - IN1/IN2 control NO1/NO2, while IN3/IN4 control NC3/NC4. Its internal charge-pump–free architecture ensures fast switching (tON = 65ns max, tOFF = 28ns max at +5V) without external timing components.
Each switch features matched RON across channels (ΔRON ≤ 4Ω at +5V), flat on-resistance over full signal range (RFLAT ≤ 18Ω), and bidirectional rail-to-rail analog conduction (VCOM, VNO, VNC = 0 to V+). Logic inputs meet TTL/CMOS thresholds (VIN_H = 2.4V, VIN_L = 0.8V at +5V), enabling direct interface with microcontrollers and FPGA I/O banks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 100Ω max at +5V supply - ensures minimal signal attenuation in precision sensor multiplexing and audio path selection. |
| On-Resistance Match (ΔRON) | 4Ω max between channels - enables accurate gain-matching in differential signal routing and multi-channel ADC front-ends. |
| Off-Leakage Current | 2nA max at TA = +85°C - preserves signal integrity in high-impedance sample-and-hold and battery-monitoring circuits. |
| Analog Signal Range | 0V to V+ - supports rail-to-rail input/output operation without level-shifting in single-supply systems. |
| Logic Compatibility | TTL/CMOS thresholds (VIN_H = 2.4V, VIN_L = 0.8V at +5V) - allows direct connection to 3.3V/5V digital controllers without interface logic. |
| Turn-On/Off Time | 65ns / 28ns max at +5V - suitable for high-speed data acquisition and communication signal switching up to 300MHz bandwidth. |
| ESD Protection | >2kV per Method 3015.7 - provides robust handling during board assembly and field deployment in industrial environments. |
Pinout & Package
MAX4612EPD+ uses a 14-pin plastic DIP (dual in-line package) with 0.3-inch body width and through-hole mounting. Pin 7 is GND; Pin 14 is V+; Pins 1, 8 are NO1/NO3; Pins 3, 11 are NC2/NC4; Pins 2, 4, 9, 10 are COM1–COM4; Pins 13, 5, 6, 12 are IN1–IN4. No exposed pad (EP) - unlike QFN variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8 | NO1, NO3 | Normally open analog output terminals - conduct only when corresponding IN1/IN3 is HIGH; used for default-open signal paths. |
| 3, 11 | NC2, NC4 | Normally closed analog output terminals - conduct only when corresponding IN3/IN4 is LOW; used for default-closed fail-safe routing. |
| 2, 4, 9, 10 | COM1–COM4 | Common analog nodes - connect to sensors, ADC inputs, or audio sources; bidirectional current flow supported. |
| 13, 5, 6, 12 | IN1–IN4 | Digital control inputs - accept TTL/CMOS logic levels; drive internal gate bias for each switch pair independently. |
| 7 | GND | Digital/analog reference ground - must be connected to system ground plane to ensure proper logic threshold referencing and leakage control. |
| 14 | V+ | Single positive supply rail - powers analog switches and logic circuitry; bypassing with 0.1µF capacitor near pin is recommended for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports 0V to V+ input/output swing - eliminates need for external level shifters in single-supply instrumentation designs. |
| Guaranteed on-resistance flatness | 18Ω max variation over full signal range - maintains consistent gain and linearity in precision analog multiplexing. |
| Low temperature drift of RON | ΔRON ≤ 4Ω from -40°C to +85°C - ensures stable channel matching across automotive and industrial operating ranges. |
| High off-isolation | -60dB at 1MHz - prevents crosstalk between active and inactive signal paths in multi-source audio/video routing. |
| Minimal charge injection | 5pC max - reduces voltage glitch and settling error in sample-and-hold and switched-capacitor circuits. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4612EUD+ | Same electrical specs, but in 14-pin TSSOP package - 5mm × 4.4mm surface-mount footprint vs. 14-pin PDIP's 19.1mm × 6.6mm through-hole layout. | Suitable for space-constrained PCBs and automated SMT assembly; not compatible with hand-soldered breadboards or socket-based test fixtures. | Select MAX4612EUD+ for volume production with reflow capability; retain MAX4612EPD+ for lab validation, legacy board upgrades, or mixed-technology assemblies. |
| ADG1412BRUZ | Quad SPST, 1.5Ω typical RON at +5V (vs. 100Ω max for MAX4612EPD+); requires dual ±15V or single +12V supply; higher bandwidth (170MHz) but larger 16-pin TSSOP package. | Targeted at high-precision test equipment and RF signal routing where ultra-low RON and low distortion are critical - not drop-in compatible due to different pinout and supply requirements. | Choose ADG1412BRUZ only when sub-2Ω on-resistance and <0.001% THD are mandatory; MAX4612EPD+ remains optimal for cost-sensitive, low-power, single-supply embedded systems. |
Compared with MAX4612EUD+, MAX4612EPD+ offers mechanical robustness and ease of manual prototyping at the expense of board area; versus ADG1412BRUZ, it trades lower RON and bandwidth for wider supply flexibility (+2V min), lower cost, and simpler single-rail power design - making it ideal for battery-operated and industrial edge-sensing applications.

FAQ
What is the maximum supply voltage for MAX4612EPD+?
The absolute maximum V+ rating for MAX4612EPD+ is +13V referenced to GND. Operation above +12V is possible but requires careful attention to supply bypassing (minimum 0.1µF ceramic capacitor placed close to Pin 14) and thermal derating. Exceeding +13V risks permanent damage to the internal CMOS structure.
Does MAX4612EPD+ support rail-to-rail analog signals?
Yes, MAX4612EPD+ supports rail-to-rail analog signal handling: the COM, NO, and NC terminals operate from 0V to V+ across the full specified temperature range. This allows direct interfacing with single-supply op-amps, ADCs, and sensors without external level-shifting circuitry.
How does the dual NO/NC configuration of MAX4612EPD+ benefit system design?
MAX4612EPD+ integrates two NO (Pins 1, 8) and two NC (Pins 3, 11) switches, enabling fail-safe signal routing - e.g., an NC path can maintain default connectivity during MCU reset or power loss, while NO paths activate only on command. This simplifies safety-critical designs like medical sensor fallback modes or industrial interlock circuits.
What is the on-resistance temperature coefficient of MAX4612EPD+?
MAX4612EPD+ exhibits a typical on-resistance increase of ~0.5%/°C from +25°C to +85°C at +5V supply. The datasheet guarantees ΔRON ≤ 4Ω across -40°C to +85°C, confirming tight tracking between channels despite absolute RON drift - critical for matched-gain multiplexer applications.
Can MAX4612EPD+ be used with a +3V supply?
Yes, MAX4612EPD+ operates down to +2V supply. At +3V, RON increases to 360Ω max (vs. 100Ω max at +5V), and logic thresholds shift to VIN_H = 1.0V / VIN_L = 0.5V. System-level validation is required for timing (tON/tOFF increase to 140ns/60ns) and THD performance, especially in audio paths.
